Tofall whom t may concern:

Be it knownv that I, JAMES M. LONGAN, a` citizenV of the UnitedStates,iresiding at Chicopee, in the county of Crawford and `State ofKansas, have invented a new and usefull Ore Washer and Separator, 'ofwhich the followingis a specification.

`The present invention relates to ore washers, `separators andconcentrators, and aims to provide a novel and improved machineforwashing various ores and separating the same from dirt and slime, ina thoroughly practical and efficient manner and with a continuousoperation;

` It is the objectl of the invention to provide a machine embodying aplurality of washing and concentrating pans or boards, and novel meansfor mounting the same for movement past areceive'r or receivers for thedischarge of the orev thereinto, the pans or boards being! agitated toconcentrate the ores therein.

A further object of the invention is the provision of a machine of thenature indicatedv wherein the pans or `boards are mounted forcircuitou's movement to provide for 'a continuous operation, theunwashed ore being'delivered onto the machine at one point, and waterbeing supplied thereon at another point, so that the washingandseparation take place as the pans are moved in succession to thereceiver to discharge thereinto.

'Iheini'fentionl also has for its object the provision of ancre washerand separator of thenature indicated embodying a novel assemblage of thecomponent elements and novelactuating mechanism, whereby the operationof the machine will be carried out in a satisfactory manner, undervarious conditions.

With the foregoing and other' objects'in view, which will appear as thedescription proceeds, theinvention: resides in the combination andarraiigementof parts and in the details of construction hereinafter deLscribed and claimed, itbeing understood that changes in the lpreciseembodiment of theinvention-herein disclosed can be made within the scopeofwhatis claimed, without departing from the spirit ofthe invention.

The inventionis illustrated in the. accom# panying drawings, wherein:

Fig. 6 is an enlarged detail view of" one of thev catches. f

Figs. 7 and 8` are plan views ofmodi'ed forms of pans or boardsusedwithlditferent ores.

The machine embodies a suitable base l above which is disposed aninclined supporting frame 2 having its lower end hinged, as at3,t'o\the`base in order that the frame can be supported at variousangles to suit various materials and? ores. The upper end of the frame 2is supported by propsV 4e or other suitable means from the base. l

The shaking or agitating frame 5' is mounted on the supporting frame 2inf a 'similarly inclined position for transverse vibratory movement,and this shaking frame embodies transverse cleats/or bars `6 seated onthe frame.` 2, and longitudinal side bars 7l securedon the cleats 6. Thecleats 16 have recesses 8 accommodating the side bars of theframe 2,permitting theframe 5 to have a limited transverse movement. The'frame 5rests against a transverseplate 9 secured upon the frame "2, therebypreventing: the shaking frame from'slidingdownwardly on the supportingframe.

In `order to shake the frame 5 transversely, reciprocatory bars; 10 arecarried by the frame 2 at the opposite' sides thereof and are providedat theopposite sideswithreversed cams or wedges 11` working in therecessesS, and the-cam bars 10 'are connected byf links or connectingrods 12 with cams or eccentrics 14 mounted on a transverse drive shaft14 carried by the frame 2 near its upper end. Thus, when the driveshaftla is rotated, the connecting rods 12-will reciprocate the cam bars 10,-thereby'actuating the cams or wedges 1l-which vibrate or `shake theframe 5 transversely and parts carried thereby; 4

'The side bars ofi theA frame. f5 areprovided with upstandinglongitudinal guidesl for the ends lofthe transverse elongated washingand separatingboards 'or pans 17g which can be constructed of wood orother-suitable material. As illustrated, said pans are each of woodhaving on the upper surfaceV the sheet metal plate 19 provided at oneedge with an outwardly curved lip or riiie 20. The ends of the pan orboard are provided with tongues 18 of reduced width to work in theguides 16 with the riiile 20 of the pan at the lowermost edge'thereof.The riiiies 2O of the pan serve to retain the oreor heavier materialwithin the pans, but permit the dirt land lighter materials to be washedfrom one pan to another with the water as it flows downwardly over theseries of pans, the rililes 2O also overlapping the next lower pans todischarge ythe materials from one pan to another toward the-lower end ofthe machine.

As a means for giving the pans a greater inclination transverselythereof when they reach the upper end of the shaking frame on which the`pans move upwardly, guides or railsy 21 are pivotally connected bylinks 22 or otherwise with the frame 5 near the upperend thereof, andextend over the upper end of said frame, being arranged at a greaterangle of inclination relative to the base 1, and at an acute angle withthe frame The upper ends of the guides 21 are adj ustably supported byadjusting screws 23 carried thereby and resting on the frame 5, orothersuitable means can be used for adjusting said guides. yThe frames 2and 5, as above explained, can be adjusted to different angles ofinclination due to the hinging of the frame 2 to the base, and theguides 21 being hingedly connected with the frame 5, can in turn beadjusted at various angles of inclination relatively to the framesaccording to the materials being worked. The guides 21 extend upwardlyat an angle from the upper ends of the guides 16, so that the pans 17 asthey are moved upwardly, move fromthe guides 16 into the guides 21, andin doing so, will begiven a greater angle of transverse inclinationlongitudinally of thefmachine, to. dump the ore into the receiver, aswill hereinafter more fully appear. The guides 21 have grooves 24 forren ceiving the'tongues 18 of the pans and said guides have cut-awayportions 25 permitting the tongues 18 to move downwardly, whereby totransfer the v pans to the returning device.v The pans when they aremoved between the guides 21 `have their tongues 18 moved over cleats 26carried by the guides beyond the recesses or eut-away portions25,thereby supporting the upper edges of the pans until the tongues 18are in a position to move downwardly, thereby causing the lower edge ofthe pan to drop, as seen in Fig. 3, while the upper edge is supported onthe cleats 26'. l

" The returning device' for the pans embodies endless belts 27 trainedaround pulleys 28 carried by the upper end of the frame 2, as at 29, andalso trained around pulley wheels 30 carried by a transverse shaft 31journaled to the frame 2 at the lower end thereof. The upper runs of thebelts 27 move downwardly underneath the upwardly moving set of panscarried by the shaking frame 5, so that when the uppermost pan dropsdownwardly from between the guides 21,it seats on the belts 27, whichconvey the pan downwardly underneath the active set of pans to the lowerend of the frame 5, where the pan is limited in its movement by suitablestops 33 carried by said frame.

The pan which is returned to the lower end of the frame 5 is transferredback into the guides 16 at the lower ends thereof, by means of a pair oflongitudinal lift bars 34 slidable longitudinally on the cleats 6 withinguides 35 thereon, said bars 34 being provided with cams 36 to move ontothe cleats 6 when said bars are moved downwardly, thereby raising saidbars. Said bars are normally slightly below the plane of the upper runsof the belts 27, but when said bars are moved downwardly and raised bythe cams 36, the bars are raised above said plane. The pan at the lowerend of the machine which rests 'against the stop 33 will, therefore, beraised by said bars into the plane of the guides 16 for upward movementinto said guides. The bars are also raised at their upper ends toreceive the pan which passes from between the guides 21, as explainedmore in detail hereinafter. These bars 34 form a part of anintermittently reciprocated trip or actuating mechanism embodying atransverse bar 38 mounted for longitudinal movement of the machine belowthe frame 5 and above the frame 2, and connected by links 37 with thebars 34 to reciprocate said bars. Cords or other fiexible elements 39are connected to the bar 38 and exl tend over guides 40 at the upper endof the frame 2 and have suitable weights 4l suspended from their freeterminals, whereby the weights normally move the bar 38 and partsconnected therewith upwardly to normal position when released. The bar38 and parts connected thereto are moved downwardly intermittently bymeans of cords or other flexible elements 42 connected to said bar andto a transverse winding shaft 43 carried by the frame 2 for winding upthe cords 42, whereby to pull the bar 38 downwardly. This shaft 43 isprovided with a star wheel 44 thereon disposed between the belts 32which connect the shafts 14 and 31 to drive the belts 27. The belts 32are connected by a series of transverse cleats 45 providing a rack tomesh with the star wheel 44 and rotate the shaft 43 to wind up the cords42 once during each circuitous movement of the belts 32. Thus, when thecleats 45 pass the star wheel 44, the shaft ITO meneer 43'zis'rotatedito` wind up` the cords 42, thus pullingthebar 38 and artsconnected thereto downwardly, and after the cleats 45 have passed thestar wheel 44, the bar` 38 is released, so that the weights 41 pull itback to normaly position. i

Upstanding `plates 46 are secured. to the endsfof the bary38 and haveconnected theretolinks 47 extending behind therlinks 22 and connectedattheirupper ends to a transverse strip 48 sliding'onthe guides 22. rThisstrip 48 isreciprocated with thebar 38, and assists in the removal ofthe pans from said guides. A transverse bar 49 is secured-upon theplates 46 above the guides 16 and frame 5, and have. secured thereon a`receiver or. collecting pan 50 which has its` upper receiving edgesoarrangedas to move below the riflies 20 in succession as the pans arefed up wardly. The receiver 50 has a discharge spout.. 51 extending toone side.

As illustrated, a singleA receiver is employed, but4 it will be readilyappreciated that a number of receivers can `be used side by side, or atdifferent positionswhen a multiple separation of the ore is desired.Various forms of pans can also be used, according to the material beingworked and other conditions. The pans shown in Figs. 1 and 3 are ofsimple or plain construction for ordinary use, whereas the. pan shown inFig. 7 is provided with oblique corrugations 60 and partition orseparating cleats 61, for use with` certain kinds of material, when theacf tion of the corrugations adds efficiency to the operation. It willbe noted that the corrugations will serve to direct the ore transverselyof the machine during the shaking and` upward movement of the pan,whereby to dischargethedesired ore into the receiver. The receivers can,therefore, be of restricted width, as seen in Fig. 1, to receive theoresfrom one point 0f the pans only, thereby providing for a more thoroughseparation of the material. Fig. 8 illustrates still another form of panhaving the cleats 61 and drain apertures 62 adjacent to the riiiies 20.These and otherforms of pans can be used as required.

In order to move the pans upwardly on the shaking frame 5, bars 52 aresecured to the bar 49 and extend downwardly along the guides 16 `overthe tongues 18 of the respective pans, and catches 53 are pivoted-to thelower ends of the bars 52 to drop intoengagement with thetonguesv 18.Said catches are reciprocated baclr and forth with the bar'38,.wherebywhen the bar 38 is moved downwardly, the catches 53 will engage thetongues 18 of thepan which is raised by the lift bars 34, the returnmovement of the bar 38, therefore, moving` the lowermost panwiththecatches 53 upwardly intothe guides 16, thereby advancingjout ofthe pans on the shaking frame. Catches` 54 arencarriedby the shakingframe near the lowerend thereof, to: engagethe tongues 18 and preventthe downward movement of the pans,` especially when the bars 52 are*moved downwardly. The bars 52 work under guides 55 carried by the'frame`5, `while the catchesV 54 work under guides. i

The* operation of the machine is as follows: The materialr to be'separated is delivered. onto thepans at the lower `portion of themachine in any suitable manner,an`d water isA sprinkled or otherwisesupplied onto the pansv to wash the dirt and lighter materialsdownwardly. During thel operationfof'themachine, theV camibars 11 willbe reciprocated continuously by the rotation of the cams 13 with theshaft 14thus shaking the frame 5 transversely. This will shake the panslongitudinally of them selves, whereby to facilitate the washing of thelighter materials from the ore, which concentrates in the pansadjacentto the riffles, serving to retain the ore. The water and` lightermaterials will flow from one pan to another over the rifHes downthemachine, thereby washing the ore. rlhe pan 17 which is in the guides 21is arranged at greater angle and its riiiie overhangs the receivingportion of the receiver 50, sothat the ore will bedischargedfrom saidpan into the receiver due to the transverse movement of said pan, thelighter materials having been previously washed from said pan during itsupward step by step movement. At intervals, the cle'atsor rack 45 of the`belt 32 will engage'the star wheel 44 and rotate the shaft 43 to windthe cords 42 thereon, lthereby moving `the bar 38 downwardly, togetherwith the links 47 and strip 48, bar 49V and receiver 50, and bars 52 andcatches 53. During such downward movement of the bar 38, the bars-34 arealso moved downwardly, whereby to lift the empty pan at the lower end ofthe machine, which has its tongues 18engaged by the catches 53. Thereceiver 50 in being moved downwardly, will `have its receiving edgemoved past and under the riilie 20 ofthe next pan. Now, when the cleats45 `have moved past the star wheel 44, thus releasing the bar 38, saidbar is re turned upwardly by` the weights 41 or equivalent means. rlhecatches 53 being moved upwardly will carry the lowermost pan with theminto the' guides 16 from the bars-34, and the lowermost pan will pushthe other pans ahead of it upwardly in the guides 16 and 21. Thereceiver 50 also moves upwardly with the pans, and the strip 48 which'was previously moved downwardly along the guides 21 over the pan17which previously discharged into the receiver, will move upwardly withsaid pan as the pan moves over the cleats 26, thusholding the pan on thecleats'26momentarily, until the tongues 180:15 Athe pancan drop throughthe cutea'way portions 25. The lower edge of the pan, therefore, dropsfirst, as seen in dotted line in Fig. 3, onto, the bars 34:, andthestrip 48 passes vover the upper edge of the pan ofl' of the same.vl/Vhen the parts have returned to normal position, the bars 3A in beinglowered let the lower edge of thev dropped pan rest on the belts Y27which carry the pan downwardly to the stops 33, said pan being cleanedout since the ore was delivered to the receiver, .and the dropping ofthe pan will also further clean it out. The pan which is moved aheadofthe receiver in moving from the guides 16 into the guides 21 will begiven a greater angle off.. inclination, thereby assisting in thedischarge of ore into the receiver in addition tothe transverse shakingmovement of the pans. The

Vtransverse shaking movement of the pans is continued in the meantime,andthe pans remain in 'their longitudinal'` position until the cleats A5again .engage the star wheel 44, when the operation is repeated asbefore. The pans move through a circuit, being moved upwardly in aseriesl to and past the receiver, and then returned to the lower'` endto again be moved up in regular order. This providesfor a continuousoperation of the machine, and a steady flow of material can be deliveredonto the machine. Each pan during its shaking movement is fed upwardlystep by stepeto `finally discharge into the receiver, and is thenreturned' back to receive another supplyv of material. The pans moveupthe incline during their shaking movement, whereby the lightermat-erials are washed downwardly from one pan to the other to bedischarged from the lowermost pan. After the dirt and lighter materialsYare washed from the ore, the ore is discharged into the receiver, thuscompletely emptying they pan automatically, whereby there is neither yanaccumulation of ore nor waste material in the machine.l Consequently,the machine need not be stopped for cleaning, and the separation of orewill be uniform, due to the fact that each pan is a unit in itself,.first receiving the material, then having the dirt and lightermaterials washed therefrom, then discharging the concentrated ore intothe receiver, and then returning back to positionV 'to receive morematerial.
